 - ✅ F-011 addressed: Slack user-name resolution now uses bounded TTL+LRU caching to prevent unbounded growth.
 - ✅ F-013 addressed: shared channel utilities now cover reset normalization/building plus reusable allowlist, mention-gating, and pairing-gating flows across Discord/Slack/WhatsApp adapters.
